Embedded systems inevitably have to deal with chip registers, and register operations require bit operations.
I won’t talk about the basic operations such as clearing a bit and setting a bit, but let’
I have used protel 99 and AD 17, and I have been drawing low-speed PCBs. Although I have been in the industry for many years, I have not studied PCB knowledge in depth. Recently, I want to learn orcad
Let us briefly discuss what is LDO.Low Dropout RegulatorA low dropout or LDO regulator is a DC linear regulator that can control the output voltage even when the input voltage provided to it is almost
Why does I2C need a pull-up resistor? Because it is an open-drain output.Why open drain output?
The I2C protocol supports multiple master devices and multiple slave devices on one bus. If push-pull ou
An important wireless technology will make its debut, Ultra-Wideband (UWB) technology. Let's take a closer look.When you think of wireless technology, the first ones that come to mind are those that h
